Remarkable SSL/TLS improvements in 2016 R1 PRE SDK, but

NETMF & Gadgeteer

…still something breaks sometimes :cry:

We’re evaluating .NETMF AMQP(s) support using G120E with AmqpNETLite library ( [url]https://github.com/Azure/amqpnetlite[/url]).

Sending scenarios of “ServiceBus.EventHub.NetMF” test project work as expected, but receiving scenarios very often (but not always!) fail, with following exception stack trace:

Running scenario ‘receive without filter’, filter ‘’…
Establishing a connection…
Creating a session…
Creating a receiver link on partition 0…

Since this is a shared project, this test could be useful to debug (native) implementation of Microsoft.SPOT.Net.Security.SslNative::SecureRead() :smiley:

Thanks!
